ROLLERBEARING.

Specication of Letters Patent.

ratented sept. 1o, 1907 Application filed December 7,1903. Serial No. 184,015.

To all 'whom il. may concern:

Be it known that I, SAMUEL S. EVELAND, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Rollenearings, of which the following is a specification.

Objects of the present invention are to facilitate the application to shafts and the like ol' hardened sleeves or bushings upon which the rollers of the bearing run; to decrease thc wear between the sleeve and the rollers; to insure smoothness and accuracy in ruiming and to provide an eliicient roller bearing hanger.

To these and other ends hereinafter set forth the invention stated in general terms comprises the improvements to be presently described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which:

Figure l is a perspective view of a two-part sleeve embodying features of the invention. Fig. 2, is a view principally in central section illustrating a hanger embodying features of the invention. Fig. 3 is a View diagrammatically illustrating blanks from which a sleeve of the character shown in Fig. l may be constructed, and Fig. 4, is a view of blanks embodying a modification of the invention.

In the drawings l and 2 are the parts or sections of the two-part or split sleeve or bushing. The edges of each of these sections are provided with alternate projections and depressions 3. 1t will be observed that the projections extend beyond a semi-circle so that they are in position to pass beyond the center of a shalt to which the parts are applied and thus clamp the part to the shaft, which is advantageous in assem- 'bling. The lines of union or abutment of the two parts of the sleeve are not straight, but are inclined and as shown, somewhat of V shape; thus the rollers 4 in passing over them travel onto a portion of the part toward which they are advancing, while they are still on a portion of the part which they are leaving. In

this way the passage of the rollers from part to part of the sleeve is smooth and without shocks or jars, whereby wear is obviated and smoothness insured. The blanks 5 in Fig. 3 are duplicates of each other and when bent into curved sections make up a sleeve like that shown in Fig. l. The blanks 6 and (Fig. 4) are different from each other, but when bent into curved shape constitute a sleeve embodying the described features of the invention.

In Fig. 2, S is a hanger housing and within it are arranged the roller bearings 9 shown as located at its opposite ends in position for their rollers 4 to run on suitable tracks or ways 10. 1I, is a shaft shown as provided with two split sleeves which embody'features of the invention and are like the sleeve shown in Fig. l.

It will be obvious to those skilled in the art to which the invention appertains that modifications may be made in details Without departingA from the spirit thereof, hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth and illustrated in the accompanying drawings, but

Having thus described the nature and objects of the invention, what I claim as new and desire to secure by Letters Patent is 1. A roller bearing having a shaft extending through and laterally beyond the same, in combination with a two part externally and internally cylindrical sleeve interposed between the shaft and bearing and divided along oblique lines into two separate parts. each part having a lateral opening of less width than the diameter of the shaft and through which the shaft may be forced to permit of springing the parts onto the shaft from the sides thereof. substantially as described.

2. A roller bearing having a shaft extending through and laterally beyond the same, in combination with a two part sleev'c` interposed between the shaft and bearing and divided along oblique lines into two separate parts, each part having :i lateral opening of less width than thel diameter of the shaft and through which the shaft may be forced to permit of springing the parts onto the shaft from thesides thereof, substantially as described.

1n testimony whereof I have hereunto signed my name.
